2019-10-29  The diameter of mineral exploration drill holes (called slimholes) is generally much smaller than the diameter of either petroleum or geothermal wells. Therefore, many of the down-hole tools used for drilling in the petroleum and geothermal fields are too large to be used in the mineral exploration

Magnetic and Gravity Methods in Mineral Exploration:

A Few BasicsGravity MethodsMagnetic MethodsSome ApplicationsData Processing and Interpretation to Detect FaultsDiversifying Geophysical EducationGravity and magnetic geophysical methods are passive. They rely on no controlled sources but seek out naturally occurring variations in the earth’s gravity and magnetic fields. For this reason, some military uses of these surveys have long included quiet detection of submarines and volatile unexploded munitions.Metamorphosed, igneous and polydeformed rocks, which are common subjects of mineral exploration, can be far more complicated than the stratified rocks examined in the search for oil an

Basic Gold Prospecting Exploration Methods

PhotogeologySeismic MethodSample ExtractionSample HandlingAssaysWhere to Look For Gold OresPhotogeology is a very important of gold deposit exploration. It gives complete information of high altitude photography and satellite photography. Images are recorded either on films or by recording the image digitally. Films used include black white, true color, and Infra-red. In color photos, the red areas indicate live vegetation. This makes them useful for locating outcrops in highly vegetated areas. Also least affected by fog, and is effective in cloudy environment. It is also good fo
